Specification
Typical application
Effectively resist voltage instability
In case of instantaneous power failure or sudden reduction of input voltage, the frequency converter reduces the motor speed to make the inertia energy on the load side feed back to the DC bus, make up for the temporary energy gap, maintain the DC voltage higher than the undervoltage action value, and avoid shutdown due to undervoltage. This function is very effective in large inertia load occasions such as centrifuges and fans.
Energy saving mode
In the energy-saving mode, the VFD will monitor the actual load size and automatically adjust and optimize the output voltage and current to make the motor run at the best efficiency point and achieve significant energy-saving effect. Relevant power data can be viewed in real time through the VFD panel to monitor the energy-saving effect. This function has obvious effect on variable torque loads such as fans and pumps.
Holding brake function
This function enables the motor to excite in advance before starting, and then open the band brake through frequency, current and other methods to prevent the load from sliding due to insufficient torque; Before the motor stops, trigger the holding brake in advance to ensure the stability of shutdown. Main applications: hoist system, crane, winch, etc
